MORE 7s Regulations

 

 

            The MORE racing organization promotes a family friendly racing organization that is dedicated fun and quality racing. The purpose of these regulations is to promote a fun and uniform class this is competitive and affordable.  These rules are subject to revision by the MORE 7s members as they see fit. The race promoter has the final say on all issues.

 

 

The goal of the regulations is to promote a fun and affordable truck racing class that is competitive. This is a class based on driver skill and ability and not having to spend large amounts of money on exotic race equipment to have fun and compete. While the class will be considered a ‘gentlemen’s class’ and rely on the honor system, the rules will be enforced by the 7s racers. All trucks will be teched prior to the race, and winners after the race. Failure to meet these rules will mean moving to the 7 open class. Participation and interaction between teams is encouraged.

 

 

Legal disclaimer- racing is dangerous. You can be injured, killed, bankrupt, divorced, or mentally challenged.  If any of this happens to you, we are not responsible for any of it, to you, your widow, girlfriends, kids, family or dead beat lawyers. There rules are not meant to keep you alive, only keep you from becoming embarrassed come race day, and there is not guarantee of that either. Theses rules are to be used by thinking people only. If you have no common sense, please remain a spectator. IF you do get hurt, killed, bankrupt, divorced, or embarrassed, do not come whining to anyone. If you are unsure of what you are doing, please ask someone smart. The persons who wrote this, kicked it around, agreed to it, the promoter, families, friends, ex-wives, dogs, estates, are not responsible for anything. These rules are merely minimum suggested requirements.  No expressed or implied warrantee of safety shall result from the publication or compliance with these rules or regulations. These are intended only as guide to orderly conduct and in no way a guarantee against injury or death to participants, spectators or others.

 

 

Tech – all 7s truck will line up for a pre-race tech. Preferable before contingency. This will allow all the 7s teams to meet each other and to look over the other vehicles. This will be a friendly event – not a ‘gottcha session”. The goal is to eliminate post-race protests due to equipment issues. Late entrants can get an early morning tech as well.

We are also going to do another pre-race photos shoot of all the trucks lined up.The photos will be FREE for all MORE7s teams.

[The term A-arms and control arms are interchangeable]

 

 

Any manufacturer spindles may be used and may be reinforced.

 

Front and rear suspensions must be of the same manufacturer, shape, size and configuration as originally produced and installed on the chassis to which it is attached.  All suspension components except shock absorbers and rear leaf springs will remain in the original stock locations with original stock mounting methods maintained.  All components with the exception of the shock absorbers must be original manufacturer’s design.

Ford specific: For model years 1998 thru 2002 the upper right two-piece A-arm is being replaced with a one-piece A-arm bearing part number of 2L5Z-3084-BA.

 

Stock front and rear track width must be retained plus or minus 2 inches as measured from brake backing plate to brake backing plate.

 

Stock sway bars may be removed.

 

All suspension components must be retained except those permitted to be removed.

 

Ford Specific:

I-beams may not be modified.  Cutting, bending, or altering geometry of the beam in any way is prohibited.  The use of spherical bearings in I-beams is permitted so long as no modifications are made to the part.  You may only press the spherical bearings into the stock end of the beam.  You may not cut or change the I-beam in any other way.

 

Radius arms may be modified to allow the use of a heim joint for the pivot.  This modification may only be done to a stock part.  You may not fully fabricate the radius arm, and you may not change the part in geometry in any way.  The radius arm may be modified only in the minimum amount to allow for the use of the heim joint.  The location of the pivot point may not be changed, and no allowance for error in mounting.  The placement must be exactly the same as the stock pivot point.  The pivot point of the radius arm will be considered the center of the mount where the rubber bushing passes through the stock cross member. 

 

A-arm Specific:

The use of any non-stock upper or lower a-arm is not permitted.  The vehicle must use the stock upper and lower a-arm.  The addition of material is permitted so long as no modifications enhance wheel travel.  Tubular A-arms are not permitted.  Mounts may be designed to use spherical bearings in place of the stock rubber so long as the pivot points remain stock.

Stock size arms only as was originally installed on the truck.

The front radius arm pivot may be modified to use a heims or unibalsl (Toyota 2wd and Nissan)

 

Leaf Specific

F.A.Q.’s

Why so many rules. No other local promoter has so many rules?

That is why the 7s racers decided to write some. Too often there is a great amount of confusion of what is and is not considered a 7s truck. We decided to clarify the issue. The goal is to create a level playing field for all competitors

 

What if I do not like one of the rules? Can it be amended or an exception made?

Maybe, depends upon the rule. The 7s racers are open to discussion. But remember, the rules are to prevent major equipment advantages and keep the racing costs down.

 

Some of the rules differ from other promoter’s rules, as they allow some back dating. Why is that. An attempt was made to include some of the older trucks. The allowances made meet the spirit of the rules, and do not allow the truck any unfair competitive advantage.  Others were done for safety reasons. Specifically these are:

Toyota-Leaf spring front ends on 86 to 85 trucks Cross over steering on 79 to 95 trucks providing a stock Toyota IFS box is used.

Ford – Removing the 4wd and using a 2wd front end. Change from an inverted T to a Y suspension.

Nissan and Toyota – allowance to convert the 2wd front radius rod to heim joint.

 

What if I do not understand a particular rule or it is a ‘grey area’?

Please bring you questions to the attention of the other 7s racers. We are more that willing to assist you.

 

I race a 7s in an other series, but they allow 4.0 motors, bent beams / tubular A-arms and coil overs. Can I still race MORE?

Sure, but your truck would be considered a 7 open truck. The 7 open class is more welcome to race with us, but will not be sharing the 7s monies.

 

What if during tech my truck is found not to be 7s legal?

Depends upon what the issue is. All trucks will be pre-raced teched. This is to prevent the dreaded post race tech protest on a tech matter. Any issues will be brought up at that time. If it is a minor issue, you may be given a one-race pass. If it is a major issue, you are welcome to race in the 7 open class.

 

Okay, so how do I join the group and get started racing in MORE?.

There are no fee's or forms to join up. Just be part of the group. Send us an email with your team and truck info. Feel free to ask any questions - we are more than willing to help you out. If you are still building a truck, let us know too. We have smart people with experince on Fords, Toyotas, Chebbies, Mazdas, you name it. We have sources for parts, vendors, shops as well. We can hook you up with team s to help out and get the real deal on off road racing.
